Your insurance company stops threatening to drop you. That’s usually the first thing homeowners notice after knob and tube wiring removal in Johnston, RI.
But the bigger shift is peace of mind. You’re not wondering anymore if that flickering light is a sign of something worse. You’re not second-guessing whether your home can handle a window AC unit or a space heater. You’re not avoiding the basement because you know the wiring looks sketchy.
Modern wiring means grounded outlets, proper load capacity, and electrical systems that can actually support the way you live now. It also means your home is easier to sell when the time comes, and appraisers aren’t flagging your electrical system as a liability. In Johnston, where over half the homes were built before 1970, an electrical system upgrade for old homes isn’t just smart—it’s often necessary to protect what you’ve invested in.
We’ve spent decades working in older Rhode Island homes, and Johnston’s housing stock is exactly the kind we know best. With nearly 40% of homes here built between 1940 and 1969, we’ve seen every version of knob and tube wiring—original installs, amateur modifications, and everything in between.
We’re licensed, insured, and members of the Rhode Island Electrical Inspectors IAEI Roger Williams Chapter. That’s not just a credential—it means we stay current on code, inspection standards, and the safest ways to replace outdated wiring in houses that weren’t designed for modern electrical loads.
We don’t oversell. If your system can be partially upgraded, we’ll tell you. If it all needs to go, we’ll explain why and walk you through what that looks like.
We start with an inspection. That means looking at your current wiring, identifying what’s knob and tube, what’s been modified, and what kind of access we have to walls, ceilings, and attics. Every home is different, so the scope depends on your layout and how much of the system needs replacing.
Once we map it out, we give you a clear estimate. No surprises. From there, we schedule the work in phases if needed, or tackle it all at once depending on your timeline and budget.
The actual old wiring removal in Johnston, RI involves running new wiring through your walls, installing a grounded system, upgrading your panel if necessary, and making sure everything is up to current code. We do our best to minimize wall damage, and when we do need to open things up, we patch and prep for paint. Most projects take one to three weeks depending on the size of your home and how much wiring we’re replacing.

You’re getting a full electrical system upgrade for old homes in Johnston, RI—not just a patch job. That means new wiring with proper grounding, updated outlets, a panel upgrade if your current one can’t handle modern loads, and everything brought up to code so it passes inspection.
We also make sure your new system can support what you actually use: multiple devices per room, HVAC systems, kitchen appliances, and anything else that pulls serious power. Knob and tube wiring was designed for a 60-amp world. Your home probably needs 100 to 200 amps now.
In Johnston, where home values have appreciated nearly 120% over the past decade, protecting that investment matters. A proper rewire doesn’t just make your home safer—it makes it insurable, financeable, and sellable. Buyers and lenders both flag knob and tube wiring, and many won’t move forward until it’s gone. Replacing it now means you’re not scrambling later when you’re trying to close a sale or refinance.
Yes, and it happens more often than most homeowners expect. Many insurance companies in Rhode Island either refuse to cover homes with knob and tube wiring or charge significantly higher premiums if they do.
Some insurers will give you a grace period to replace it—usually 30 to 90 days after they discover it during an inspection or claim. Others won’t renew your policy at all. And if you’re shopping for new coverage, you’ll find that most carriers ask about your electrical system upfront.
The reason is straightforward: knob and tube wiring is a fire risk. The insulation deteriorates over time, the system wasn’t designed for modern electrical loads, and there’s no grounding. Insurers don’t want that liability, so they either price it into your premium or walk away entirely. If you’re in Johnston and you’ve been told your wiring is an issue, knob and tube wiring removal is usually the only way to restore full coverage.
For most two-story homes in Johnston, you’re looking at somewhere between $4,250 and $9,000 or more, depending on the size of your home, how much wiring needs replacing, and whether your electrical panel also needs an upgrade. Add another story, and the cost typically goes up about $2,000.
The price varies because every home is different. Some houses still have knob and tube wiring throughout. Others only have it in certain rooms or circuits. Access matters too—if we can run new wire through an unfinished basement or accessible attic, the job is faster and less invasive than if we’re working around finished spaces.
It’s not a small expense, but it’s also not optional if you want to keep your insurance, sell your home, or stop worrying about fire risk. Most homeowners in Johnston who go through with it say the peace of mind alone was worth it. And if you’re planning to stay in your home long-term, it’s an investment that protects your property value and keeps your electrical system safe for decades.
No, and doing that actually makes the problem worse. Knob and tube wiring was designed to be open to air so it could dissipate heat. When you bury it in insulation, the wires overheat, the old insulation breaks down faster, and the fire risk goes up.
A lot of homeowners don’t realize this until they’re mid-project on an attic or wall insulation upgrade and a contractor flags it. At that point, you’re stuck—you can’t insulate safely until the wiring is replaced, and you can’t leave the wiring exposed if you want your home to be energy efficient.
This is especially common in Johnston, where older homes are often being renovated to improve comfort and lower heating costs. If you’re planning any kind of insulation work and you know you have knob and tube wiring, it’s worth addressing the electrical system first. Otherwise, you’ll end up paying for the same work twice.
Most projects take between one and three weeks, depending on the size of your home and how much of the system we’re replacing. A smaller home with partial knob and tube wiring might be done in a few days. A larger home where we’re rewiring the whole house will take longer.
We work in stages when it makes sense—especially if you’re living in the home during the project. That means we’ll focus on one section at a time, keep the power on as much as possible, and coordinate with you so you’re not left without electricity for days on end.
The timeline also depends on whether we need to upgrade your electrical panel, how much wall access we have, and whether there are any surprises once we open things up. Older homes in Johnston sometimes have wiring that’s been modified over the years, and that can add time if we need to address safety issues that weren’t obvious during the initial inspection. We’ll give you a realistic timeline upfront and keep you updated if anything changes.
That depends on what your insurance company requires, what your local inspector will approve, and what’s actually safe. In some cases, you can get away with replacing only the circuits that are actively used or that feed high-load areas like kitchens and bathrooms.
But here’s the reality: most insurance companies and home inspectors want it all gone. Even if some of the knob and tube wiring is still in decent shape, it’s old, it’s ungrounded, and it’s not built for how homes operate today. Partial removal might buy you time, but it usually doesn’t solve the insurance problem or the safety concern.
If budget is tight, we can phase the work—start with the most critical areas and finish the rest later. But if you’re already opening walls and bringing in an electrician, it often makes more sense to do it all at once. You’ll avoid paying twice for mobilization and labor, and you’ll have a fully upgraded system that you don’t have to think about again.
You’ll have a harder time. Buyers will either ask you to replace it before closing, request a price reduction to cover the cost themselves, or walk away entirely. Lenders are also wary—some won’t approve a mortgage on a home with knob and tube wiring because of the fire risk and insurance complications.
Even if you find a cash buyer who’s willing to take it on, you’re still leaving money on the table. Homes with outdated electrical systems appraise lower, and buyers know they’ll need to budget thousands of dollars for rewiring as soon as they move in.
In Johnston, where home values have climbed significantly over the past decade, it doesn’t make sense to let old wiring drag down your sale price. Most sellers who replace knob and tube wiring before listing see a smoother transaction, fewer inspection issues, and better offers. If you’re planning to sell in the next few years, replacing the wiring now gives you time to enjoy the upgrade and positions your home as move-in ready when it hits the market.
